摘要:
The popularly used backpropagation algorithm (BP) for training multilayered neural networks is generally slow and prone to getting stuck in local minima. In this paper, a novel method to improve the performance of BP by randomising the cost function is proposed. The method is effective in helping the BP algorithm to escape from local minima and therefore improve convergence and generalization. This is demonstrated on a non-convex pattern recognition problem.
